TE Connectivity – Make first, break last connector offers superior grounding performance


TE Connectivity (TE) has added a product with Make First, Break Last (MFBL) functionality as part of its POWER TRIPLE LOCK line of connectors.

The new MFBL connector’s application- specific grounding design permits the ground connection to be established before power connections are made, and maintains the connection until the power connections are broken. This capability fulfils a key requirement of a variety of mid-range power connections in appliances and commercial building equipment.

Using TE’s proven POWER TRIPLE LOCK connector design, the MFBL connector can facilitate easier assembly and more secure connections than other pin-and-socket connector solutions.

The three-position, wire-to-panel or wire-to-wire MFBL connector is based on a 6.0mm centreline pitch. Like other POWER TRIPLE LOCK connectors, it is rated for 600V AC or DC. The MFBL connector features a 12A maximum current and accepts wire up to AWG 16.

The MFBL connectors offer polarisation and keying to help prevent connector mis-mating, an anti-snag design, and a locking mechanism to help secure connections when the cap and plug latch together. For additional reliability, an optional connector position assurance device helps prevent the connector from being mistakenly disengaged.
